My first game of A&A was with a college buddy who owned the game. He hadn’t played it much himself, and I was learning the game from him, so you can imagine the mess we made of the rules. He took the Axis once, and the Allies once. In each game, he bought IC’s, then proceeded to capture territories and place them in the newly won areas THE SAME TURN. Also, when he took over a territory with an IC, he IMMEDIATELY placed all the units he’d bought on it. We also didn’t know there was supposed to be something called “limited production” at any IC. . .
Imagine Germany buying 7 tanks and 4 men, storming Karelia, then plunking down all the new hardware in Karelia that very turn. Yep, our games didn’t last very long :-P
